Embodiment Construction

[0010] Such as figure 1 As shown, a double-filtering rainwater recovery treatment system includes a first filter 1 and a second filter 2. The first filter 1 is composed of a tubular body with a large diameter in the middle and small diameters at both ends. The inner wall of the lower end and the inner wall of the middle part are connected by an inwardly protruding water interception platform 3, and a filtered water outlet 4 is arranged at the water interception platform 3; on the second filter 2 An inlet and an outlet are set, an inclined notch 5 is provided below the inlet of the second filter, and a filter screen 6 is arranged on the inclined notch 5, and the filtered water outlet of the first filter 1 4 communicates with the inlet of the second filter 2.

[0011] The inner side of the water intercepting platform 3 protrudes upwards.

[0012] The filtered water discharge port 4 is arranged obliquely downward.

Abstract

The invention relates to a dual-filtration rain recycle processing system, which comprises the first and second filters, wherein the first filter is formed by tubular element whose middle is large and two ends are small; the inner wall of low end and the inner wall of middle part are connected via cutoff table that protruded inwards; the cutoff table is arranged with one filter water outlet; the second filter is arranged one inlet and one outlet; one incline groove is under the inlet of second filter; the groove is arranged with filter screen; the filtered water outlet of first filter is connected to the inlet of second filter. The invention can separate the foreign matter in rain by simple rain recycle processing system, to confirm clean rain.

Description

technical field [0001] The invention relates to water treatment technology, in particular to a purification and recovery device for natural precipitation, in particular to a rainwater recovery and treatment system with double filtration. Background technique [0002] In the prior art, water is the most precious resource for human beings, but due to human waste and pollution, clean water sources are becoming less and less. Now, almost all countries in the world suffer from water shortage. The problem of water shortage in our country is more serious, especially in the northern regions of our country. For this reason, the state dismantles huge sums of money to carry out the project of diverting water from the south to the north. Even if the project is successfully completed, it can only meet the water needs of some areas, and cannot fundamentally solve the serious water shortage problem in the northern region. Rainwater, as a source of clean water, is receiving attention. No...
